Pa. shale gas production doubled from 2011 to '12

Pennsylvania's Marcellus and other shale deposits produced more than 2 trillion cubic feet of natural gas in 2012, continuing a trend of production growth despite fewer drilling rigs in the field.

Pennsylvania's Marcellus and other shale deposits produced more than 2 trillion cubic feet of natural gas in 2012, continuing a trend of production growth despite fewer drilling rigs in the field.

New production data reported by natural gas drilling companies and released by the state Department of Environmental Protection on Tuesday showed that 1.1 trillion cubic feet of gas flowed from unconventional wells in the state during the second half of 2012.

The wells produced an average of 6.2 billion cubic feet of gas per day between July and December, or enough to fulfill about 9 percent of the nation's daily natural gas demand. The U.S. consumed about 70 billion cubic feet of natural gas per day in 2012, according to the U.S. Energy Information Administration.

The state's shale gas production doubled between 2011 and 2012, even as the number of rigs drilling new wells in Pennsylvania dropped in response to lower gas prices and companies migrating to more lucrative deposits in other states. The annual average number of drilling rigs operating in Pennsylvania declined from 110 in 2011 to 84 in 2012, according to oil field services company Baker Hughes.

In reports released last week and in January, the EIA said it expects that Marcellus Shale production will continue to grow despite relatively low natural gas prices as drilled wells are tied to an expanding network of pipelines. It also suggested that increased rig efficiency will maintain production levels, even as the number of active rigs has declined.

Energy analysts say Marcellus production is still constrained by limited pipeline infrastructure, especially in the northeast corner of the state.

Northeast Pennsylvania wells dominated the biannual production report, as they had in past reporting periods. All but three of the top 25 wells were in Susquehanna or Wyoming counties.

Bradford County remained the top-producing county in the state with 285 billion cubic feet of gas coming from 609 wells.
